How Adaptive Server and Open Client interact depends on how you determine Open Client capabilities. Specifically, “capabilities” refer to the types of requests an application sends on a specific connection and the types of server responses that a server returns for a specific connection. Before you use Open Client with the wider limits allowed by Adaptive Server 15.0, enable Open Client capabilities for these limits and modifying your code. See the Open Client Client-Library/C Reference Manual for information about enabling the wide-table capabilities.
DB-Library™ cannot use the wide limits for
Adaptive Server 12.5 and later. Wider columns were introduced with
Adaptive Server and Open Client 12.5. If you wrote applications
with Open Client 12.5.1, they can connect to Adaptive Server 15.0.
However, to take advantage of additional features in Adaptive Server
15.0, you may need to recompile with Open Client 15.0.
New features for Open Client 15.0 include:
Wider identifiers – objects such as table names, column names, and so on now support up to 255 bytes.
Scrollable cursors.
New datatypes – 8-byte integer, unicode, and text.
